I got ripped off at the US nationals one year. I would always change out of my street cloths into my driving suit before a run. So we go to the staging lanes and close our trailer up but didn't lock it. The theif went into my trailer and took my credit cards out of my wallet and put my wallet back into my pants.
When I got the motel that night I noticed them missing. When I called my credit card company they had already turned them off since the criminals had already spent like $5000 at a golf store and others. They knew I wasn't golfer since I always used them for racing purchases.
Luckly both cards were platium cards? and I didn't have to pay anything.
The next day at the track I told NHRA about it and they sent there detectives to talk to me. Said it has happened before and they(thiefs) send runners out right away and use the cards before they are turned off.
So we started locking up everything each time we ran the car.
